definitely turn it on ( -d 1 )
good and bad above --> probably wont affect your disk transfer speed
as much as turning on dma mode ( -d1 )

good ... udma5 is ata66 ... 66MB/sec disk xfer

nope... in your other post... you said
x> 486DX2-25, 64M RAM, all ISA(PNP), 850M + 30G HDD
those ide controllers on those oldies ( mb ) probably doesnt support
ata66....
than find out which chipset is on that pci card
( probably promise chipset for maxtor ata66 controllers )
and turn on the dma option in the kernel ...
and even "echo ide-module-name" might work too.. donno
and one more thing ... "hdparm -d1 -u1 -X69 -c3 /dev/hde"
and than see what happens "hdparm -tT /dev/hde"
btw.. you probably wont be able to boot from /dev/hde
but can use /dev/hda as your lilo/grub mbr stuff and
root=/dev/hde .. major happyness at that point on a 486 box ??
you probably want to get a pci-based ide controller and plug it in
and use that pci-based ide controller to talk to your ata-66 fujitsu
MPG3307AT
have fun
